Application filed March 4, 1915. Serial No. 11,977. l

To all 'whom it may concern Be it known that I, REGINALD H. CAMP- BELL,a citizen of the United States, and a resident of the city of Kankakee,in the county of Kankakee and State of illinois, have invented certainn-ew and useful Improvements in Book-Markers; and Iv do hereby declarethat the following 1s av full,

clear, and exact description of the same,

reference being had to the accompanying drawings, and to the numerals ofreference marked thereon, which form a part of this specification.

- This invention relates to an improved type of book marker wherein aplurality of marking devices are adjustably associated with retainingmeans toafforda convenient means of marking the different pages in thebook desired for reference as well Vas the particular line or paragraphon a page referred to. p

It is an object therefore of this invention to construct a book markingdevice consisting of inserts adapted to be placed between the pages of abook and detachably retained in position by means disposed at each endof the book, and with marking devices movably secured to each of saidinserts to serve as a finding tab at the outer edge of the book and alsoafford a means of indicating particular line upon a page. Y

. itis also an object of this invention to construct book marking deviceof fieXible nature to permit distortion thereof Vwith bending of theleaves of the book, and with flexible retaining means attachable at eachend of the book to hold the same at all times, in proper position in thebook.

it is furthermore an importantobject of this invention to provide a bookmarking device embracing a plurality of inserts attached at each end ofthe book upon resilient spring members and readily removable therefromand provided with movable indicating means adapted to be adjusted to anydesired position between the pages to alford a finding tab at the edgeof the book, the entire device being removable as a whole from the bookWithout requiring disassembly of any of the parts.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

In the drawings: Figure l is a plan view of a book in open positionshown equipped with a device embodying the principles of 'taining meansof the device.

my invention. Fig. 2 is a fragmentary end view thereof. Fig. 3 is afragmentary plan view of one of the inserts and indicating elementsshown detached from the retaining means and from the book. Fig. 1i is a.view similar to Fig. 2, illustrating the book bent open and showing theflexibility of the parts. Fig. 5 is a detail of one of the spring snaprings used in connection with the re- Fig. 6 is a fragmentary sectiontaken on line Gw of Fig. 3. Fig. 7 is a side edge view of the end of oneof the indicating elements. Fig. 8

is a fragmentary plan view illustrating a modified means of connectingan indicating element to a page insert. Fig. 9 is a fragmentary sectiontaken on line 9 9 of Fig. S.

As shown in the drawings, the covers of a book are denoted by thereference numorals l, and the pages by the reference numerals 2, thecovers 1, being flexible to permit bending thereof, as clearly shown inFig. 4f. Disposed between certain pages of the book to which referenceis to be made, are marking or insert strips of flexible material such astransparent Celluloid, each denoted by the reference numeral 3, and eachhaving at its ends apertures t, therethrough. As clearly shown in Figs.l, 2, and 1i, said inserts 8, are placed between the pages 2, close tothe back or binding of the book, and where a number are used smallcoiled flexible springs 5, are provided at each end of the book whichengage through the apertures 4, ofthe inserts to retain any one thereoffrom displacement when the book is opened to a particular page, such asshown in Figs. l and 4L, at which such an insert is disposed. A finechain 6, having a closed eye 7, at one end thereof engaged through aloop at one end of the spring 5, is provided, and at its other end has aspring latch ring 8, which may be opened for disengagement from the loopat the other end of the spring 5, when it is desired to attach or detachone of the inserts 3, to or from said spring.

Movably mounted upon each of the page marker inserts 3, are indicatingelements 9, one end of which, as clearly shown in Fig. 6,

` is folded over upon itself to afford a loop for engagement around themarker insert 3. At the other end of each of said indicating elements 9,which are preferably of transparent flexible Celluloid, is an indicatingtab, which is formed by dipping the end of the element in an opaquecelluloid solution to forni a coating ll0, thereon, which is properlylettered with a character, such as illustrated infull and in dottedlines in F ig. 3, as 17 and thereafter being dipped in a transparentCelluloid solution to form a protective coating ll, thereover.

In Figs. S and 9, I have illustrated a modified means of attaching anindicating element, denoted by the reference numeral 12, to al pagemarking insert 3, and for this purpose said indicating element 12, isprovided With'aiienlarged rounded end 13, having a slot therethroughpermitting the ieXible indicating element 12, to be folded around theinsert 3, and inserted through.

the slot, thus forming a slip loop around said insert, which permitsdetachment of the indicating element therefrom, as Well as a' slidingmovement thereon. Y

Ifdesireda memorandum card lll, maybe attached upon'anyrone or all ofthe indicating elements of the device' in a manner illustrated in Fig.ll, bymerely cutting slots in the card and engaging the card upon theindicating element, and the card may then be lettered on both sidesthereof to afford reference ineniorandunis to the reader for either ofthe pages of the twoshe'ets between which said indicating element isdisposed.

rIhe operation is as 'follows Inasmuchas there is a retaining means ateach end of the book the page marking inserts 3, may be first attachedupon one of the springs 5, and then inserted between the pi'oper. pagesof theV Vbook to rwhich reference is to be subsequently made.Y The otherspring 5, is then inserted through the apertures 4, at the other end ofY the marking strip inserts, the snap ringY 8,

being detached-from the end'of 'the spring 5, for the purpose. After theinserts have been engaged on said latter spring, thesnap ring 8, isagain engaged upon the end'of theV Y springg-so that there is nopossibility ofthe Vwith the Yin arking insert. j Y ments constitutingthe device are flexible, so

,i thatthere is no possibility of injuring the i retaining meansslipping out of engagement All of the eleed thereon at the outer end ofsaid element aifords a finding means, permitting the reader to turnimmediately to the page desired. Y

I ain-aware that various details of construction may be varied through aWide range Without departing from the principles of this invention, andI therefore do not purpose limiting the. patent granted other-Q Wisethan necessitated'by the prior art.

I claim as my inventionz; 1 ,Y Y l. In a book marking device of the..class described, a pluralityV of flexible Vpage inserts having aperturesin each end thereof,

coiled springs extending through said aptures, and detachable means onsaid springs Y to retain them in operative position.

2. In a device of the classfdescribed, iii-- serts adapted to be ,placedbetween the pages of a book and having apertures in the endthereof,'coiled springs inserted through the Y apertures ofsaid-inserts, one of said'mem-"jfV bers disposed at eachend of the book,andV detachable means thereon to retain'said inserts in operativeposition in said members. 3. In a'device of the class described, the

combination with a book, of marking means therefor comprisinga pluralityof adjust-V able strips insertible between the pages of;

the'book, and coiled springs,one disposed at `each endf of thebookandconnectedto the projecting ends of said strips Vto maintain thesaine associated with thebook. I
